This invention relates to new and useful improvements in burnishing machines and particularly to portable machines for burnishing silverware and like articles.

The principal object of the invention is to provide a burnishing machine of the "character set forth for burnishing hotel and restaurant table silverware which is portable as a complete unit from place to place.

Another object .of the invention is to provide a device of the character set' forth embodying novel structure permitting the articles of silverware to be discharged therefrom without handling by the operator. A further object of the invention is to provide a device of the character set forth which is constructed and operable in such manner as to not require plumbing connections therewith for drainage and the like.

Other features and details of the invention are .set forth hereinafter and shown in the accompanying drawing in which:

Fig. l is a side elevational view of the device constituting the invention; and

Fig. 2 is an end elevational view of the disclosure set forth in'Fig. 1.

The present invention is constructed and adapted for use in public dining rooms scenes hotels anddining rooms wherein the'large numsberof pieces of table and silverware in use must be cleaned at relatively frequent intervals.

.Heretofore, .the majority of 'burnishing or polishing machines employed in the cleaning of table .silverwareas set forth above, have been large, cumbersome machines and of necessity stationary. In addition the majority of these machines comprise generally a horizontal tumblingdeviceimounted ina tub and areoperated in such a manner that requires permanent plumbing connections with the various .parts thereof .for drainage purposes.

.By the present invention a .burnishing machine is provided which is portable as a complete, selfecontained unit, and is constructed vandloperatesin a mannerand upon a principle which entirely eliminates the necessity for permanentpiped connections therewith for drainageor other purposes. The present device is of, relatively light weight and may .be easily movedfr'om one place ofnconvenience to another for operation. .Inadidtion, the invention contemplates .the provision .of means operatively associated with the burnishing machine to enable .the silverware to be discharged from 7 the :barrel at will and accordingly eliminates the heretofore customary but necessary method of removing the samemanually.

liteierring now more particularly to the drawing," the device made in 'acordance with the present invention comprises a horizontal sup porting member'lor tray 1 having its edges bent obliquely upward'as at Z'to provide side and end walls for the purpose of retaining articles thereon. The tray 1 'in the presentinstance is mounted upon the upper en'ds of a plurality of legs 3, and as shown in the drawing, a swivel caster or support {1 is mounted in the lower end of each of the legs 3 for a' roller 5'whichis rotatably mounted in the said swivel supports or casters l, said roller being fabricated entirely of rubber or provided with a'peripheral covering of rubber asmay be desired sfor't he purpose'fiof rendering movement of the machinesubs'tane tially noiseless. A tray or'support 6 is mounted in a horizontal position between each of the legs 3 adjacent the lower ends thereof.

In the present instance a pair of upstanding brackets '7, 7 are permanently secured to the upper surface of the tray 1 and these brackets ar'eequally spaced with respect to the lon itudinal' axis of said trayat opposite sides there'- of and adjacent one end of theflmaclnne.

The extremities of' a pair 'of parallel arms 9 which project from a holloiv'easing'qr housing 10 are pivotally .rncunted with'respcot tofthe brackets 7, '7 by means of arod or bar 1 1 which extends through aligned apertures in said arms 9, .9 and ibrackets' 'l, 7 as shown in Figi' 2. support .12 is mounted atone side of the housing" or casing 10 and -,in the presentinstanee an electric or other type of motor 13 ismounted thereon by means of bol-ts 14. A worm l5 isfr otatably journaled in the bellow casing 10 adiacentlthe upper endthfileof, referencebeing'had to Fig. Land-the outer end of the said worm 15 is'directly connected to the shaft 15 of the motor .13 by means of a .fl'exible coupling 17. A worm wheel 18 isiixed ona shaft 19 whichis also rotatably journaled in the casing 19in oil-less bearings 20 and the teeth of this gear lfi meshwith theaforementioned worm 15' which is drivenbytthemotor l3.

A tumbling barrel 21 is permanently mounted upon theforward extremity, oftheshait leand arranged to berot atably driven thereby through gears; 15 and 1 8.previcn sly setforth. The construetion of the tumbling barrel \or container 21 and; its cover member 22 is substantially the same as'shoyvn and describe'd in .U. S. Letters Eatent 1,911,312 iissuedlto' Fred rick c. Qood,

May 30, 1933, and need not be reiterated here.

A rib 23 of substantially U-shape is formed on the inner adjacent faces of the brackets 7, '7 in proximity to the upper end thereof, as shown in Fig. l and this rib 23 circumvents the pivotal connection of the arms 9, 9 to the said brackets in spaced relation with respect thereto as shown. When the barrel is in a horizontal position as shown, the inner upper end 23a of the rib 23 extends in substantially parallel spaced relation with respect to the adjacent edge surface of the arms 9, 9 to permit the entrance between the in Fig. 2 about its pivot point the wedge or spacer 24 will be displaced from between the rib 23 and arm 9 and permit the barrel 21 and housing 10 to pivot about the bar or rod 11 in a clockwise direction with respect to Fig. 1,

. so that the opening of the barrel will be declined at an angle sufficient to cause the silverware and bur-nishing material to be discharged therefrom during the course of usual rotation thereof. The rear or outer upper end of the rib 23 is -inclined upwardly and outwardly at an acute angle as at 231) and the angular disposition of this portion of the rib 23 is such that when the barrel is pivoted about the bar or rod 11 in a counter-clockwise position with respect to ,Fig. 1, the outer or rear end edge surface of the arms 9 will rest upon this end of the rib 23 and the weight of the barrel will act to maintain itself in this position which approximates the vertical.

In the present instance a container 27 rests upon the tray 1 and is disposed, as shown, below the right-hand or discharge end of the barrel 21. The container 27 is provided with an inner mesh receptacle 28 into which the barrel discharges, in the manner previously set forth, the

silverware at the end of a burnishing operation as well as the burnishing materials such as the shot and chemical soap. The mesh of the receptacle 28 should be sufiiciently coarse so 1 that when the same is lifted outwardly of the container 27 the shot and other burnishing materials discharged thereinto from the barrel 21 with the silverware will fall or drop therethrough into the container 27 and leave only the silverware in the receptacle or basket 28.

The container 2'7 is provided with a spout or chute portion 29 at one end thereof for the purpose of facilitating return of the burnishing materials to the barrel 21 for a succeeding burnishing operation.

In operation of the device the pivotally mounted wedge or spacer 24 controls the movement of the barrel to various positions. When the barrel is lifted or pivoted to a substantially vertical position, as previously described, it balances itself and when dropped or pivoted to a nishing materials which is accomplished by allowing the barrel 21 to continue rotating.

While the features and details of the invention have been specifically set forth for the purpose of description, it is not intended that the invention be wholly limited thereto except such as is not within the scope of the annexed claims.
